Ok, Vger's MX is heading off to point to subspace on Thursday. Web services are staying put for now, so if you link to / use Vger it's staying put (possibly with a massive OS upgrade coming).
The fundamental infrastructure isn't going anywhere even if it has to change it's name, and should lists not want to head off to subspace, infradead, etc I've got https://vger.email up and running and capable of picking things up should anyone want to jump.
End of an era, Vger's been independent of kernel.org from it's start, but it's a non-trivial set of lists that literally keep the Linux kernel community moving, and has since it's inception. It's realistically needed an upgrade to deal with a plethora of problems, and frankly various large e-mail providers have made it nearly untenable to keep doing without it nearly being a full time job (at least at the scale that Vger's at)
